| Abstract: | Based on the boring machine's fault protection features,a new data collection method,namely the improved full-wave Fourier algorithm,was proposed.On the basis of criteria for over-current,negative sequence and zero sequence current fault the algorithm for sequence component was deduced.Its performance was tested through static simulation and test.The data collection method was proved to be stable,reliable,accurate and rapid,and has important applications in significantly improving the operation performance,... |
